Design Manual for Artificial Reefs
Artificial reefs are wave-breaking structures artificially constructed from rubble to mimic the wave-control functions of coral reefs. Since these structures are located below sea level,...
Development of Offshore Breakwaters for the Marine Multipurpose Zone Project
Under these circumstances, the ministry of construction of Japan has launched the marine multipurpose zone (MMZ) project,and is promoting the effective use of seashores facing the open...
A Study on Fishing Port Structures in Harmony with Fishery Environment
We have reported on the concept of environmentally productive fishing port structures along the coastline of Japan ('91 LONGBEACH). In this paper we present a field model experiment on...
Japan's Port Management and The United States' Port Management
Management systems vary between ports, as well as between countries. Some systems are nationally centralized and others are relatively independent from government control. Between Japan...
Development of the Long Caisson Type Vertical Breakwater
The width of the caisson of a breakwater is calculated based mainly on the wave force expected to act on the caisson. IN this calculation, the assumed wave force is the peak wave force...
Development of the Double Cylinder Caisson Breakwater
A double cylinder caisson breakwater was recently developed to create a calm sea area in deep and high wave open sea areas. In order to confirm some subjects on design method and construction...
Ecolocy-Conscious Submerged Breakwater
A submerged breakwater makes incident rough waves small when their heights exceed a certain level on the site, though the other waves lower than the level are not so much affected by the...
Filtering and Prediction on Freeways Using Markov Models
A Markov compartment model of freeway traffic flow is presented and used to derive a Kalman Filter which tracks a freeway section's density, broken down by destination. The filter is then...
Field Implementation and Testing of a Machine Vision Based Incident Detection System
This paper contains test results of a video detection device installed in the field for over two years and the development and field deployment of an incident detection sysytems called...
Video Image Processing Application: Automatic Incident Detection on Freeways
This paper presents the results of tests carried out in the last 3 months of 1992 regarding the Automatic Incident Detection System elaborated in the INAVID project (DRIVE program). This...
Image Measurement Systems for Traffic Analysis?Specifications, Survey, and Limits
This presentation is concerned with systems for extraction of road traffic information from visual images. The extracted information ranges from macro-scale, cumulative traffic parameters...
Design Hydrographs in Coastal Wetland Watersheds
The use of synthetic unit-hydrographs for hydraulic design in ungaged watersheds has been an accepted practice for over 50 years. In southeastern U.S. coastal regions, which contain extremely...
Stochastic Generation of Daily Low Flows in Estuaries for Salinity Intrusion Studies
Stochastic data generation technique was used to provide a probabilistic approach to a salinity intrusion/low flow study of an estuary in West Malaysia. The Kemaman River on the east coast...
Stochastic Modeling for Drought Analysis
Periodic as well as annual stochastic streamflow models have been fitted to the highly variable flows measured at Krishnarajasagara (KRS) on river Cauvery (Southern India), which is monsoon-dependent...
Stochastic Modeling for Drought Analysis Using Thomas-Fiering Lognormal Three Parameter Model
Three variations of Thomas-Fiering log normal 3-parameter(TFLN3) model are fitted to the unregulated south-west monsoon-dependent monthly streamflows measured at Krishnarajasagara (KRS)...
Dynamic Perspective on the Capillary Barrier Effect at the Interface of an Upper Fine Layer with a Lower Coarse Layer
The theoretical principles behind the determination of infiltration rate into a coarse layer overlain by a tight layer are reviewed. As a descending unsaturated wetting front hits the...
Kinematic Mixing in Stratified Aquifers
The mixing process in heterogeneous aquifers is presented as the bending and stretching of material lines. A linear mixing efficiency is defined in terms of the mean values of a unit length...
Muskingum Basin Reservoir Pool Frequency Analysis
The purpose of the study was to develop a consistent and defendable elevation frequency analysis of pool elevations for sixteen reservoirs within the basin. A significant level of interest...
Modeling Two-Dimensional Subsurface Flow, Fate and Transport of Microbes and Chemicals
A two-dimensional model to simulate the subsurface flow, microbial growth-degradation, and transport and biodegradation of chemicals in groundwater environments (2DFATMIC) is developed....
A Unified Approach to Flood Frequency Analysis
Most stochastic hydrologic studies are based on statistical distributions that are pre-selected without giving consideration to the applicability of the distribution to a particular data...
